Features

ESD Considerations: The DFX II force gauge may turn OFF if a high voltage ESD

discharge occurs to the output shaft. In the unlikely event that a high voltage discharge occurs, please turn back ON the DFX II force gauge and it will operate normally.

When designing custom ﬁxtures ensure the load rating of the custom ﬁxtures

exceed the load rating of the load cell in the force gauge being used. i.e. If the load cell is rated for 100 LBF the custom ﬁxtures should have a load rating greater than 100 LBF.

The DFX II Series have the following standard features:

l +0.3% of Full Scale Accuracy l Large, Easy-to-Read LCD Display l Selectable Units (ozf, gf, lbf, kgf, N) l Lockable Units l Normal and Peak Measurement Modes l Selectable Languages (English, French, Spanish,

Portuguese, German, Chinese)

l Automatic Power Save Shutdown l Battery Operation 70 to 100-hours of

Introduction

The Chatillon

DFX II Series digital force gauges is a battery-operated force indicator. It uses a NiMH bat-

tery for power. It may also be used with the DFX II battery charger/charger (included) supplied.

The DFX II Series may be used to measure and display tensile or compressive loads at an accuracy of +0.3% of full scale. The DFX II Series may also be set to capture the peak tensile or compressive load. The DFX Series is available in four models having four different capacities and user-selectable units of measurement.

Display Layout

The Chatillon DFX II Series has a high resolution, dot-matrix LCD, 8 lines, 21 characters. Display contrast is set at the factory and requires no adjustment. The load bargraph, at the bottom of the display, indicates the load currently being applied to the internal load sensor. The bargraph ﬁlls from the center location with tensile loads measured to the left and compression loads measured to the right. A load direction indicators shows whether the applied load is tensile or compressive.

Selecting Mode

The DFX II Series has three measurement modes: Normal, Tension Peak (T-PK) and Compression Peak (C-PK). Select the Peak key to display the peak load measured in tension or compression. Use the zero key to clear the peak reading and to prepare the gauge for the succeeding measurement.

Change Mode

View Peak Result

The Chatillon DFX II Series will display the peak (maximum) load achieved for a test. There are two methods to view peak results:

1. Place gauge in Normal mode. Apply a push or pull force against the load sensor. Select the PEAK key. View the peak result.

Using The Battery Charger

The DFX II Series may be battery operated or operated using the battery charger accessory (SPK-DF2-UNIV). When the battery charger is used, the internal batteries are charged. The battery charger may be plugged into a 115V or 230V source power outlet. The battery charger contains three interchangeable plug styles: USA, EURO and UK.

1. Place the correct plug onto the battery charger.

Use the Chatillon Battery Charger that comes with

IMPORTANT

the DFX II Series digital force gauge.

Do NOT use generic battery chargers. These can

permanently damage the gauge electronics.

Note

The DFX II will display “Recharge Battery” when the

battery voltage drops to approximately 4.5VDC

To charge the DFX force gauge plug the phone jack of the supplied universal battery charger into the DFX force gauge then plug the battery charger into the correct AC power outlet. Ensure the correct power is applied to the battery charger. Never plug the USA 2-prong 115VAC charger into a 230VAC power source. To obtain a full charge it is recommended the DFX force gauge is charged for 15-20 hours. The DFX force gauge should get approximately 70 to 100 hours of battery life on a single charge.

A battery icon appears on the main operating display and operates like a bar graph. When the gauge has a full charge, the battery icon appears full. As the battery voltage diminishes, the battery icon will start to empty. You may view the estimated battery life based on current usage in hours by depressing the “i” key until the battery life screen appears.

3. Plug the battery charger into the DFX II power input.

2. Plug the battery charger into the source power outlet.

4. Press the DFX II On/Off key to turn power ON.

The DFX force gauge will alert you when the battery assembly needs to be recharged by adding a message to the main test screen “Recharge Battery”. The force gauge will shutdown automatically if the battery voltage reaches approximately 4.5VDC.

CAUTION: Do not attempt to charge the Chatillon DFX series force gauge with any other charger than the one supplied with

the force gauge or supplied by an authorized

Chatillon dealer. The nickel metal hydride batteries are

temperature sensitive and the battery charger is speciﬁcally design to properly charge this battery assembly without damaging it.

Reversing the Housing

The DFX II Series comes from the factory with the measuring shaft located at the bottom of the gauge when reading the display.

In applications where the measuring shaft is required to be at the top of the gauge, simply reverse the housing.

1. Turn power to the gauge OFF.

2. Remove two (2) 6/32 screws on the gauge housing using Hex key supplied with the DFX II.

3. Rotate the top housing 180-degrees being careful not to strain or damage the internal wiring.

DFX II gauges shown with top housing reversed.

4. Re-assemble gauge housing using two #6-32 hex screws.
